5.1.3.30 IfcRelAssociatesClassification
5.1.3.30.1 Semantic definition
The objectified relationship IfcRelAssociatesClassification handles the assignment of a classification item (items of the select IfcClassificationSelect) to objects occurrences (subtypes of IfcObject) or object types (subtypes of IfcTypeObject).
The relationship is used to assign a classification item, or a classification system itself to objects. Depending on the type of the RelatingClassification it is either:
- a reference to an classification item within an external classification system, or
- a reference to the classification system itself
The inherited attribute RelatedObjects define the objects or object types to which the classification is applied. The attribute RelatingClassification is the reference to a classification, applied to the object(s). A single RelatingClassification can thereby be applied to one or multiple objects.
